5 of 5 Best Charger Ever December 17, 2022
Reviewer: Steve Klein from Somers Point, NJ USA NJ United States  
This charges everything! Get one! I have a dozen 18650 Li-ions that I thought were dead. This restored them and saved me, at least, $150. It's paid for itself 4 times over. I've come across some 21700 batteries that would not fit in other chargers. They fit in this charger. They also have great customer service. They have a phone # and a human being actually answers it. Just try that with Amazon or Ebay. You can get the best price on any of their products on their website, the nitecorestorestore. Start your own account with them and get notified of special offers.
